By refusing to get married, Asha will damage her family¿s reputation and ruin her younger sister¿s chances of finding a good husband. Will Asha choose to follow her heart, to go to college and …


Avian Seed Dispersers Of The Invasive Rubus Niveus (Rosaceae) In The Galapagos Islands, Ecuador, Monica C. Soria Nov 2006

Avian Seed Dispersers Of The Invasive Rubus Niveus (Rosaceae) In The Galapagos Islands, Ecuador, Monica C. Soria

Theses

The foraging behavior of bird assemblages at Rubus niveus was determined over two seasons in the agricultural zone of Santa Cruz Island, Galapagos in order to identify effective seed dispersers of the species and understand the factors that aid invasion of fleshy fruited weeds. A total of seven bird species were observed feeding on R. niveus fruits. In both seasons, the small ground finch (Geospiza fuliginosa), the introduced smooth-billed ani (Crotophaga ani ) and the small tree finch (Camarhynchus parvulus) were the most common visitors. Mean number of seeds removed per visit was higher for …


Assessing Ecological Correlates Of Avian Disease Prevalence In The Galapagos Islands Using Gis And Remote Sensing, Shane Robert Siers Oct 2006

Assessing Ecological Correlates Of Avian Disease Prevalence In The Galapagos Islands Using Gis And Remote Sensing, Shane Robert Siers

Theses

In recognition of the potential consequences of pathogen introduction to the Galapagos Islands, the Saint Louis Zoo and the University of Missouri¿Saint Louis, in cooperation with the Galapagos National Park Service and the Charles Darwin Research Station, implemented an avian disease surveillance program in 2001, with the objective of identifying and monitoring for pathogens that pose risk for native bird populations. The purpose of this thesis is identify environmental factors that might influence the geographic distribution of avian pathogen infection, based on two data sets obtained as a result of these surveillance efforts: 1) seroprevalence data on 10 common poultry …


Durationalism: Temporalism And Eternalism, Adam Patrick Taylor Jul 2006

Durationalism: Temporalism And Eternalism, Adam Patrick Taylor

Theses

An ongoing debate among propositionalists centers on the question: can the truth values of propositions change over time (?). The view that says that propositions can change truth values over time has been called temporalism. The more traditional view of propositions, which denies temporalism, and goes back to Frege, has been called eternalism. Mark Richard has given forceful argument against temporalism and in favor of eternalism: the argument from belief retention. On Richard¿s view, if temporalism comes out true then it is impossible for one to retain one¿s beliefs over time. As an eternalist about propositions, I believe that all …


Evolutionary Implications On Contextualism, John Mark Gowan Jul 2006

Evolutionary Implications On Contextualism, John Mark Gowan

Theses

Contextual knowledge-attribution and natural selection are both processes that allow knowledge-attributions and organisms to evolve, respectively. The difference between Contextual knowledge-attribution and natural selection is the existence of intention: natural selection is an unintentional process that is possible because of random physical variations while Contextual knowledge-attribution is an intentional process that is possible because of random memetic variations. Evolutionary Contextualism, as a memetic theory, is the theory that knowledge-attributions evolve based upon unequal probabilities within a context created by falsifiable standards that are dependent upon attributer intentions. If Contextualism is a memetic theory that concerns knowledge, and memetic evolution is …


Two Contemporary Approaches To The Individuation Of Concrete Particulars: Why A Substance Theory Is A Stronger Account, Nicholas Paul Spitzer Jul 2006

Two Contemporary Approaches To The Individuation Of Concrete Particulars: Why A Substance Theory Is A Stronger Account, Nicholas Paul Spitzer

Theses

Throughout the history of philosophy, philosophers have explained the nature of those ordinary objects of common sense like dogs, cats, trees and people in many different ways. One of the problems that arise upon giving an account of the nature of these objects (philosophers call them concrete particulars) is the problem of individuation. The problem arise upon trying to explain what it is about the nature of a concrete particular, that makes it the very same thing as itself and not another? To put it another way, what is it about any individual concrete particular that makes it distinct from …


Two Degrees Of Intentionality: Approaching The Ascription Of Psychological Content In Non-Linguistic Creatures, Michael Joseph Ferreira Jul 2006

Two Degrees Of Intentionality: Approaching The Ascription Of Psychological Content In Non-Linguistic Creatures, Michael Joseph Ferreira

Theses

We often include intentional (psychological) states in the explanation of complex non-human animal behavior. How, if possible, should we characterize intentionality in other species without trivializing our own? I aim to develop a strategy, compatible with intentional realism, for approaching the ascription of intentionality in non-linguistic species. One way to approach the question, one rehearsed in multiple contexts, is to question the conditions under which conceptual mental representations might obtain in non-linguistic species. I follow a similar, but less developed strategy. I argue, following some recent literature, that it is likely that concepts split into (at least) two kinds. If …


Patterns Of Habitat Use By Primates In Eastern Ecuador, Seema Nayan Sheth Jun 2006

Patterns Of Habitat Use By Primates In Eastern Ecuador, Seema Nayan Sheth

Theses

Lowland tropical rain forests of western Amazonia are characterized by the most speciose primate communities in the Neotropics, immediately leading to the question of to what extent does niche partitioning by primate species serve as a mechanism to promote species co-existence. Because the primate assemblages that we observe today reflect a combination of ecological and evolutionary processes, this study examines habitat occupancy and its relationship to phylogeny and space in a diverse diurnal primate community in an undisturbed lowland rain forest of Amazonian Ecuador. Specifically, the following null hypotheses are explored as potential factors that shape community structure: (1) mean …


Rise: A Robust Image Search Engine, Debangshu Goswami Apr 2006

Rise: A Robust Image Search Engine, Debangshu Goswami

Theses

This thesis advances RISE (Robust Image Search Engine), an image database application designed to build and search an image repository. rise is built on the foundation of a CBIR (Content Based Image Retrieval) system. The basic goal of this system is to compute content similarity of images based on their color signatures. The color signature of an image is computed by systematically dividing the image into a number of small blocks and computing the average color of each block using ideas from DCT (Discrete Cosine Transform) that forms the basis for JPEG (Joint Photographic Experts Group) compression format. The average …


Anti-Individualism And Rationality, Adam J. Arico Apr 2006

Anti-Individualism And Rationality, Adam J. Arico

Theses

Paul Boghossian has argued that externalist descriptions of mental content are unfit for assessments of rationality. An individual, he suggests, can comport with the principles of logic and rationality if and only if she is able to introspectively recognize the content of her thoughts and beliefs without relying on empirical evidence. Jessica Brown argues, first, that Boghossian¿s notion of rationality is unrealistic and incompatible with modern experimental data, and second, that his principles of transparency of mental content are unreasonable and, ultimately, self-defeating. In defending Boghossian¿s notion of rationality, and subsequently his transparency principles, this paper attempts to respond to …
